Reattachment of fractured fragment of an anterior tooth: case report and nine-year follow-up.

This article reports the treatment and follow-up of a 10-year-old boy who had a politraumatic accident that resulted in severe displacement and fracture of the maxillary right central incisor. After clinical and radiographic examination, the tooth fragment was bonded with adhesive and the tooth crown underwent nonrigid splinting. Follow-up appointments were scheduled once a week during the first month, once during the second month, and every three months thereafter. Each follow-up appointment included a clinical examination, followed by radiographic and pulp sensitivity tests. After the fifth year, pulp necrosis was diagnosed following a sensitivity test and a periapical radiograph. Endodontic treatment was performed; the chemical-mechanical preparation and root canal fillings used calcium hydroxide paste manipulated with saline solution. The abovementioned paste was replaced twice during the first month; after that, propylenoglycol was used as the vehicle for manipulating the calcium hydroxide. The filling paste was replaced whenever the radiographic image showed resorption of the paste. The root canals were filled definitively seven years postaccident. Nine years postaccident, clinical and radiographic examination revealed a normal aspect.
